Bound states in the continuum and long-range coupling of polaritons in hexagonal boron nitride nanoresonators
Harsh Gupta, Giacomo Venturi, Tatiana Contino +6
Bound states in the continuum (BICs) garnered significant for their potential to create new types of nanophotonic devices. Most prior demonstrations were based on arrays of dielect…
High quality factor polariton resonators using van der Waals materials
Michele Tamagnone, Kundan Chaudhary, Christina M. Spaegele +6
We present high quality factor optical nanoresonators operating in the mid-IR to far-IR based on phonon polaritons in van der Waals materials. The nanoresonators are disks patterne…
Guided Modes of Anisotropic van der Waals Materials Investigated by Near-Field Scanning Optical Microscopy
Daniel Wintz, Kundan Chaudhary, Ke Wang +11
Guided modes in anisotropic two-dimensional van der Waals materials are experimentally investigated and their refractive indices in visible wavelengths are extracted. Our method in…
Gate-controlled mid-infrared light bending with aperiodic graphene nanoribbons array
Eduardo Carrasco, Michele Tamagnone, Juan R. Mosig +2
Graphene plasmonic nanostructures enable subwavelength confinement of electromagnetic energy from the mid-infrared down to the terahertz frequencies. By exploiting the spectrally v…
Nonlocal Electromagnetic Response of Graphene Nanostructures
Arya Fallahi, Tony Low, Michele Tamagnone +1
Nonlocal electromagnetic effects of graphene arise from its naturally dispersive dielectric response. We present semi-analytical solutions of nonlocal Maxwell's equations for graph…
Predicting input impedance and efficiency of graphene reconfigurable dipoles using a simple circuit model
Michele Tamagnone, Julien Perruisseau-Carrier
An analytical circuit model able to predict the input impedance of reconfigurable graphene plasmonic dipoles is presented. A suitable definition of plasmonic characteristic impedan…
Fundamental limits and near-optimal design of graphene modulators and non-reciprocal devices
Michele Tamagnone, Arya Fallahi, Juan R. Mosig +1
The potential of graphene for use in photonic applications was evidenced by recent demonstrations of modulators, polarisation rotators, and isolators. These promising yet prelimina…
Graphene Antennas: Can Integration and Reconfigurability Compensate for the Loss?
Julien Perruisseau-Carrier, Michele Tamagnone, Juan Sebastian Gomez-Diaz +1
In this opening presentation we will first recall the main characteristics of graphene conductivity and electromagnetic wave propagation on graphene-based structures. Based on thes…
Reconfigurable THz Plasmonic Antenna Concept Using a Graphene Stack
Michele Tamagnone, Juan Sebastian Gomez Diaz, Juan Ramon Mosig +1
The concept and analysis of a Terahertz (THz) frequency-reconfigurable antenna using graphene are presented. The antenna exploits dipole-like plasmonic resonances that can be frequ…
